If you have an iphone or ipod touch 4, I recommend Harry's Lap timer app. It's $16 and you can use the lap timer and live video simultaneously. Very easy to use and high accuracy with a separate GPS receiver. My brother has this setup.

I use an older ASUS Windows Mobile PDA with Racechrono free app. Not quite as easy to use but more in-depth analysis. The stand-alone Racechrono Pro GPS works great for $549.
